BUILDING CNSTRUCTION.

application 'med December 15`, 1921. smal no. 522,659.

To all whom t may concern Be it known that THnonom; J ULIUS JOHN ALmacH'r, a subject of the King of Great Britain, residing at Manukau Road, New Lynn, Auckland, New Zealand, in the Provincial District of Auckland, has invented certain new and useful Im )rovements in Building` Construction, of which the following is a specification.

This invention relates to constructions erected in terra-cotta, concrete and the like and has for its object the provision of an improved construction, whereby walls of bulldings and the like may be erected so as to be damp-proof, lire-proof and earthquake resisting, and at the same time, be rendered ornamental, and everlasting. y

In order to carry outthe erection `of a wall according to the invention, the former is built up of pre-moulded hollow blocks containing dove tailed recesses in their upper surfaces and formed with dove tailed tongues projecting from their underneath surfaces, the tonguesv of 4the blocks of each course engaging in the recesses-of the blocks comprising the course, immediately beneath 1n such a manner that said horizontal courses are made to interlock with each other.

The blocks 4of each horizontal course, are

courses v immediately and are formed with holes upper and lower surfaces, permitted to pass vertically wall. 4

' The blocks are formed with a vertical rebate in each end, lthe rebate in `one end, being however at the opposite side of the block to the rebate in t e other end.

By these means the blocks vof each course through their whereby air is throughout the can be` fitted into each other,\ instead of` merely butting against each other and thus provide forV a strong joint being made, and

p at the same time are enabled tol be formed all from the same mould.

Both sides of the blocks can be vertical and formed to provide a 'wall with `flush sur-v faces, or the outer' sides or surfaces of the blocks can be sloped and made to overlap, to give'weather boarding effect to the wall.

Each block preferably contains a vertical longitudinal wall, which divides the interior of the block into compartments whichI are made to communicate with each other.

The'ends of blocks used at the corners of buildings have bevelled ortions adjoining their inner surfaces and rifrht angle portions adjoining their outer sur aces with vertical ha f dove tailed recesses located between said -bevelled-and right angle portions. Hal-f blocks, when the latterare necessar to complete courses have ends similarly ormed.

The half dove'tailed recesses, when the of a. wall constructed 4according lto the invention and Figure 2 is a tion of walls. V

Figure 3 is an elevation of the parts shown in Figure 2 and Figure 4 is a vertical section taken through the line A-A, Figure 3.

Each block 1 is made hollow and has a dove tailed recess 2 in its upper surface and a dove. tailed tongue 3 'projecting from its underneath surface, the. tongues 3 of the blocks of a course being slid-endways into the recesses 2 of the blocks of the course beneath, thereby locking the courses together.

The blocks 1 are also each formed with a vertical rebate 4 in each end, the rebate in one en'd of a block being however at the op posite side of the latter to the rebate 4 in the other end of the block.

This enables the blocks 1 to fit into each other instead of merely butting the one against the other and enables a strong joint to be made, as greater surfaces are obtained for groutingthe blocks of the courses together than if the joints were simply straight across the wall. A

plan view showing a junc- The blocks 1 of each course are made to I* break jointwith the blocks 1 of the courses immediately above and'below and provision ismade for permitting the passage of air vertically throughout the wall, as well as horizontally through the latter, by forming holesm through the upper and lower surfaces of the blocks, the holes in the different courses bennade to register, so that communication tween the an' spaces of the lcourses is obtained.

' between which is established by extending the holes into the partitions (i, as shown in ure 4.

'he ends of blocks used at the corners of buildings or at the unctions of walls are formed with bevelle portions 8 extending outwards from their inner surfaces and with right angle portions 9 extendingl inwards from their outer surfaces, while between the bevelled portions 8 and right angle portions 9, vertical half dove tailed recesses 10 .are provided. Y

Half blocks 11 when requiredto complete courses are formed with ends, similar to that just described.

lVhen the end blocks of adjoining walls are placed in position, the vertical haldovc tailed recesses 10 provide a complete vertical dove tailed recess into which are slipped vertically, the vertical dove tailed tongues l2 projecting from the inner corners of flat sided vertical blocks 13 which are fitted between the right angle portions l9 of the end blocks of the adjoining walls. y

The blocks 13 are grouted together and each contains a vertical hole 14, whereby a continuous vertical passage i's formed in the blocks 13, throughout the height of the wall.

and may be utilized as a down' pi e for the conveying away of water and the like.

The sides ofl the blocks can be madevertical and so as to give flush surfaces to the wall, as shown at 15 Figure 4, or they may be slopedl and made to overlap on their outer surfaces, in order that the external surface of the erected wall, will have the appearance of weather boarding as/at 16 Figure 4.

What I do claim and desire to obtain by Letters Patent of the United States of America, is i A block for usein building walls and like structures including a substantially rectangular hollow body also rectangular in cross section, a vertical longitudinal partition positioned parallel to and medially of the side walls of the body and extending throughout the length thereof and integral with the u per portion of the body so as to divide t ie same into parallel compartments and the u per and lower portions of the body and t e adjacent portions of the partition being provided with openings which are situated in alignment which the adapted to register wit openings in the adjacent blocks so as to place the compartments of each block in communication with each other and in communication with the compartments of the adjacent blocks.

In testimony whereof I have'alixed my signature.
